Abstract

"COMPOSIçãO POLIMéRICA DE ESPUMA EXPANDIDA DE CéLULA ABERTA, PAINEL DE ISOLAMENTO ACúSTICO E FOLHA DE ESPUMA COMPREENDENDO DITA COMPOSIçãO". A presente invenção provê uma composição polimérica de espuma expandida de célula aberta compeendendo pelo menos uma poliolefina linear ou linear modificada, pelo menos 50% das células sendo abertas, e as células tendo um tamanho médio de pelo menos 1 milímetro. é desejável que a composição tenha um coeficiente de absorção acústica, conforme determinado por ASTM 1050 em 1.000 Hz que seja maior que 0,15. Nas espumas preferidas a composição tem uma resistividade a fluxo de ar inferior a cerca de 800.000 Rayls/m.
